OPERATIONS

OPERATIONS

Gamma Knife Operations

Gamma Knife stereotactic radiosurgery, a non-invasive procedure, is an alternative to conventional brain surgery and/or radiation therapytherapy. It can be an adjunct to conventional brain surgery, radiation therapy, or chemotherapy. Compared to conventional surgery, Gamma Knife radiosurgery usually is an out-patient procedure with lower risk of complications and can be provided at a lower cost. Typically, Gamma Knife patients resume their pre-surgical activities one or two days after treatment. The Gamma Knife Perfexion unit, which was introduced by Elekta in 2006, treats patients with 201192 single doses of gamma rays that are focused with great precision on small and medium sized, well circumscribed and critically located structures in the brain. The Cobalt-60 sources coverageconverge at the target area and deliver a dose that is high enough to destroy the diseased tissue without damaging the surrounding healthy tissue. During 2006, Elekta introduced a new Gamma Knife model, the Perfexion™ unit (“Perfexion”), which treats patients with 192 single doses of gamma rays. In 2015, Elekta introduced an upgrade to the Gamma Knife Perfexion unit called Icon. Fourteen (14)As of March 1, 2021, all of the Company’s seventeen (17)thirteen (13) Gamma Knife units in the United States are Gamma Knife Perfexion units.

units and two (2) of these Perfexion units have the Icon upgrade.

The Gamma Knife treats selected malignant and benign brain tumors, arteriovenous malformations, and functional disorders including trigeminal neuralgia (facial pain). Research is being conducted to determine whether the Gamma Knife can be effective in the treatment of epilepsy, tremors, and other functional disorders.

As of December 31, 2017,2020, there were approximately 118116 Gamma Knife sites in the United States and more than 330345 units in operation worldwide. Based on the most recent available2019 case mix data, an estimated percentage breakdown of Gamma Knife procedures performed in the U.S. by indications treated is as follows: malignant (61%(65%) and benign (23%(21%) brain tumors, vascular disorders (4%), and functional disorders (12%(10%).

The Company, as of March 1, 2018,2021, had sixteen (16)thirteen (13) operating Gamma Knife units located in the United States and onetwo (2) in South America in Lima, Peru.Peru and Guayaquil, Ecuador, respectively. The Company’s first Gamma Knife commenced operation in September 1991. The Company’s Gamma Knife units performed 1,6311,530 procedures in 20172020 for a cumulative total of approximately 39,00043,500 procedures from commencement through December 31, 2017.

2020.

As December 31, 2020, the Company recognized a loss on the write down of impaired assets of $8,264,000. The impaired assets included six (6) Gamma Knife units and related removal costs, and two (2) deposits towards the purchase of proton beam systems and related capitalized interest. The six (6) Gamma Knife units that were impaired consisted of two (2) units that had been taken out of service in prior years, one (1) unit that was taken out of service in 2020 and three (3) units that have already, or the Company anticipates will be taken out of service in 2021, totaling $3,051,000. In addition to this impairment write-off of $3,051,000 were estimated costs of de-install and removal (ARO) of four (4) of the Gamma Knife units of $1,350,000 (of which, the Company has paid $80,000) as of December 31, 2020. Total impairment related to the Gamma Knife business was $4,401,000 for the year ended December 31, 2020.
The Company reviews the carrying value of its long-lived assets for impairment on a quarterly basis, or as events or circumstances might indicate that the carrying value may not be recoverable. The Company has reviewed its Gamma Knife equipment, in light of available information as of December 31, 2020 and based on current customer prospects, the probability of future contract extensions or renewals, and the high turnover rate in contract terminations compared to the Company's historical contract termination rate, the Company determined that these six (6) Gamma Knife units were more-than temporarily impaired.
Gamma Knife treatment was included in the Radiation Oncology Alternative Payment Model (“RO APM”). However, for the Company's customers included in the RO APM, there does not appear to be a significant reimbursement impact.
Revenue from Gamma Knife services for the Company during each of the last five (5)two (2) years ended December 31, and the percentage of total revenue of the Company represented by the Gamma Knife for each of the last fivetwo years, are set forth below:

Image GuidedAdvanced Radiation Therapy OperationsEquipment and Services

The Company is continuing its efforts to contract new radiation therapy customers both domestically and internationally. The Company has increased its product offerings from standard linear accelerators to more advanced linear accelerators that incorporate Magnetic Resonance Imaging (“IGRT”MRI”)

and potentially Positron Emission Tomography (“PET”) imaging technologies. The Company believes that these more advanced technologies, with a higher capital cost component, may be potentially a more receptive market segment for its business model.

Table of Contents
The Company’s radiation therapy business currently consistsconsisted of one IGRTImage Guided Radiation Therapy (“IGRT”) system that began operation in September 2007 at an existing Gamma Knife customer site. Revenue generated under IGRT services accounted for approximately 3% of the Company’s totalThis contract terminated in July 2020 and did not generate any revenue in 2017.

IGRT technology integrates imaging and detection components into a state-of-the-art linear accelerator, allowing clinicians to plan treatment, verify positioning, and deliver treatment with a single device, providing faster, more effective radiation therapy with less damage to healthy tissue.  IGRT captures cone beam imaging, fluoroscopic and/or x-ray images on a daily basis, creating three-dimensional images that pinpoint the exact size, location and coordinates of tumors. Once tumors are pinpointed, the system delivers ultra-precise doses of radiation which ultimately leads to improved patient outcomes.

Based on the most recently available information, there are approximately 3,900 linear accelerator-based radiation therapy units installed in the United States, and it is estimated that a majority of these units provide Intensity-Modulated Radiation Therapy (“IMRT”), IGRT or a combination of this advanced radiation therapy capability. Radiation therapy services are provided through approximately 2,300 hospital based and free-standing oncology centers.

Proton Beam Radiation Therapy Operations

(“PBRT”)

PBRT is an alternative to traditional external beam, photon-based radiation delivered by linear accelerators. PBRT, first clinically introduced in the 1950s, has physics advantages compared to photon-based systems which allow PBRT to deliver higher radiation doses to the tumor with less radiation to healthy tissue. PBRT currently treats prostate, brain, spine, head and neck, lung, breast, gastrointestinal tract and pediatric tumors. In excess of 160,000More than 200,000 patients have been treated with protons worldwide.

Prior to December 31, 2020, the Company had $2,250,000 in deposits toward the purchase of two MEVION S250i PBRT systems from Mevion. The Company reviews the carrying value of its deposits for impairment on a quarterly basis, or as events or circumstances might indicate that the carrying value may not be recoverable. The Company has reviewed the deposits, in light of available information, as of December 31, 2020 and based on its current customer prospects, the impact that the COVID-19 pandemic has had on medical centers undertaking large capital expenditure projects for a limited patient base, and the length of time required to negotiate and implement a proton therapy project, the Company determined that its deposits of $2,250,000, related capitalized interest of and other charges of $1,613,000 were other-than temporarily impaired. Total impairment related to the proton therapy business was $3,863,000.
Introduction of PBRT in the United States, until recently, has been limited due to the high capital costs of these projects. The Company believes that the current development of one and two treatment room PBRT systems at lower capital costs and the level of reimbursement for PBRT from the Centers for Medicare and& Medicaid Services (“CMS”) will help make this technology available to a larger segment of the market.

However, the introduction of the RO APM and the inclusion of PBRT in this model potentially limits the adoption of PBRT by medical centers.

Additional information on our operations can be found in Item 6– “Selected Financial Data”, Item 7– “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and Note 1 of our consolidated financial statements.
CUSTOMERS

The Company’s typical fee per use agreement is for a ten-year term. The fixed fee per use reimbursement amount that the Company receives from the customer is based on the Company’s cost to provide the service and the anticipated volume of the customer. The Gamma Knife contracts signed by the Company typically call for a fee ranging from $6,000 to $9,300 per procedure. There are no minimum volume guarantees required of the customer. In most cases, GKF is responsible for providing the Gamma Knife and related ongoing Gamma Knife equipment expenses (i.e., personal property taxes, insurance, and equipment maintenance) and also helps fund the customer’s Gamma Knife marketing. The customer generally is obligated to pay site and installation costs and the costs of operating the Gamma Knife. The customer can either renew the agreement or terminate the agreement at the end of the contractual term. If the customer chooses to terminate the agreement, then GKF removes the equipment from the medical center for possible placement at another site.

The Company’s typical revenue sharing agreements (“retail”) are for a period of ten years. Instead of receiving a fixed fee, the Company receives all or a percentage of the reimbursement (exclusive of physician fees) received by the customer. The Company is at risk for any reimbursement rate changes for radiosurgery or radiation therapy services by the government or other third-party payors. There are no minimum volume guarantees required of the customer.

At December 31, 2019, three customers each individually accounted for 12%, 15% and 30% of total accounts receivable, respectively.

MARKETING

The Company markets its Gamma Knife services through its preferred provider status with Elekta and a direct sales effort led by its Senior Vice President, of Salesits President, Chief Operating and Business Development, its Chief OperatingFinancial Officer, and its Chief Executive Officer. The Company markets its PBRT service through a direct sales effort led by its Senior Vice President, of Salesits President, Chief Operating and Business Development, its Chief OperatingFinancial Officer, and its Chief Executive Officer. The major advantages to a health care provider in contracting with the Company for its services include:

§The medical center avoids the high cost of owning the equipment. By not acquiring the equipment supplied by the Company, the medical center is able to allocate the funds otherwise required to purchase and/or finance the equipment to other projects.

§The Company does not have minimum volume requirements, so the medical center avoids the risk of equipment under-utilization. The medical center pays the Company only for each procedure performed on a patient.

§For contracts under revenue sharing arrangements, the Company assumes all or a portion of the risk of reimbursement rate changes. The medical center pays the Company only the contracted portion of revenue received from each procedure.

§The medical center transfers the risk of technological obsolescence to the Company. The medical center and its physicians are not under any obligation to utilize technologically obsolete equipment.

§The Company provides planning, installation, operating and marketing assistance and support to its customers.

FINANCING

The Company’s Gamma Knife business is operated through GKF. GKF generally finances its U.S. Gamma Knife units, upgrades and additions with loans or capitalfinance leases from various finance companies for typically 100% of the cost of each Gamma Knife, plus any sales tax, customs, and duties. The financing is predominantly fully amortized over an 84-month period and is collateralized by the equipment, customer contracts and accounts receivable, and is generally without recourse to the Company and Elekta. The loan to finance the Company’s unit in Peru is guaranteed by GKF and collateralized by the Company’s stock in the subsidiary, GKPeru. The lease financing obtained by Orlando is guaranteed by the Company and collateralized by the equipment, customer contract and accounts receivable related to this project.

COMPETITION

Conventional neurosurgery, radiation therapy and other radiosurgery devices are the primary competitors of Gamma Knife radiosurgery. Gamma Knife radiosurgery has gained acceptance as an alternative and/or adjunct to conventional surgery due to its more favorable morbidity outcomes for certain procedures as well as its non-invasiveness. Utilization of the Company’s Gamma Knife units is contingent on the acceptance of Gamma Knife radiosurgery by the customer’s neurosurgeons, radiation oncologists and referring physicians. In addition, the utilization of the Company’s Gamma Knife units is impacted by the proximity of competing Gamma Knife centers and providers using other radiosurgery devices.

Conventional linear accelerator-based radiation therapy is the primary competitor of the Company’s proton therapy system at Orlando Health. ProtonAlthough proton beam radiation therapy althoughhas been available for many years, it is only recently emerging as a more clinically beneficial alternative to conventional linear accelerators for certain tumors. Utilization of the Company’s proton therapy system is dependent on the acceptance of this technology by Orlando Health’s radiation oncologists and referring physicians, as well as patient self-referrals. There are currently no competing proton therapy facilities in close proximity tonear the Company’s site.

There are several competing manufacturers of PBRT systems, including Mevion, IBA Particle Therapy Inc., Hitachi Ltd., Varian Medical Systems, Inc. (Accel), Hitachi Ltd., ProNova Solutions, LLC, Sumitomo Heavy Industries, ProTom International, Inc. and Mitsubishi Electric. The Company has purchased one MEVION S250 and has made deposits towards the purchase of two additional MEVION S250S250i systems. The Mevion system, as well as single room proton therapy systems from other manufacturers, potentially provides cancer centers the opportunity to introduce single treatment room PBRT services with a cost in the range of approximately $25$30 to $35$40 million versus four and five PBRT treatment room programs costing in excess of $120 million. The MEVION S250 system received FDA approval in the second quarter of 2012 and the first clinical treatment occurred in December 2013 at Barnes-Jewish Hospital. The MEVION S250i (Hyperscan) unit, which includes pencil beam scanning, was FDA approved in December 2017. The Company’s first MEVION S250 system in operation at Orlando Health treated its first patient in April 2016. The Company currently does not have customer contracts for its second and third PBRT units.

The Company believes the business model it has developed for use in its Gamma Knifestereotactic radiosurgery equipment and IGRTadvanced radiation therapy placements can be tailored for the PBRT market segment. The Company is targeting large, hospital-based cancer programs. The Company’s ability to develop a successful PBRT financing entity depends on the decision of cancer centers to self-fund or to fund the PBRT through conventional financing vehicles, the Company’s ability to capture market share from competing alternative PBRT financing entities, and the Company’s ability to raise capital to fund PBRT projects.

The Company’s ability to secure additional customers for Gamma Knifestereotactic radiosurgery equipment, advanced radiation therapy equipment and services and other proton beam radiation therapy services, or other equipment, is dependent on its ability to effectively compete against the manufacturers of these systems selling directly to potential customers and other companies that outsource these services. The Company does not have an exclusive relationship with any manufacturer and has previously lost sales to customers that chose to purchase equipment directly from manufacturers. The Company may continue to lose future sales to such customers and may also lose sales to the Company’s competitors.

GOVERNMENT PROGRAMS

The Medicare program is administered by CMS of the U.S. Department of Health and Human Services (“DHHS”).Services. Medicare is a health insurance program primarily for individuals 65 years of age and older, certain younger people with disabilities, and people with end-stage renal disease, and is provided without regard to income or assets.

The Medicare program is subject to statutory and regulatory changes, administrative rulings, interpretations and determinations, requirements for utilization review, and federal and state funding restrictions, all of which could materially increase or decrease payments from these government programs in the future, as well as affect the cost of providing services to patients and the timing of payments to our client hospitals.

The Company’s Gamma Knife PBRT and IGRTPBRT customers receive payments for patient care from federal government and private insurer reimbursement programs. Currently in the United States, Gamma Knife and proton therapy and IGRT services are performed primarily on an out-patient basis. Gamma Knife patients with Medicare as their primary insurer, treated on either an in-patient or out-patient basis, comprise an estimated 35%-45% of the total Gamma Knife patients treated nationwide. PBRT and IGRT patients with Medicare as their primary insurer are treated primarily on an out-patient basis and comprise an estimated 45% to 50% of the total radiation therapy patients treated.

Congress enacted legislationOn September 18, 2020, CMS issued the final rule that would implement a new mandatory payment model for radiation oncology services: the RO APM. The RO APM is scheduled to commence January 1, 2022 and will be in 2013effect for a five (5) year period. The RO APM significantly alters CMS' payment methodology from a fee for service paradigm to a set reimbursement by cancer type methodology for radiation services provided within a 90 day episode of care. Under the RO APM, hospital based and free-standing radiation therapy providers are mandatorily required to participate in the model based on whether the radiation therapy provider is located within a randomly selected Core Based Statistical Area ("CBSA"). CMS projects that significantly reducedproviders treating approximately 30% of radiation oncology patients have been selected to participate in the RO APM. The remaining providers not included in the RO APM will continue to receive reimbursement based on a fee-for-service methodology. The RO APM includes but is not limited to PBRT and Gamma Knife services. Four (4) of the Company's Gamma Knife centers are scheduled to be included in the RO APM. It is not anticipated that inclusion in the RO APM will have a significant impact on the Company's Gamma Knife revenues. The Company's PBRT center was not selected for inclusion in the RO APM. For centers not included in the RO APM proposed model, Medicare reimbursement ratein 2021 for outpatient Gamma Knife treatmentthe most commonly used PBRT delivery codes increases by setting it at the same amount paid for linear accelerator-based radio surgery treatment. Prior to April 1, 2013, Medicare’s reimbursement rateapproximately 4.1% and decreases by approximately 1.7% for Gamma Knife treatment had been relatively stable. Congress’s enactment of the American Taxpayer Relief Act of 2012, however, reduced Medicare’s Gamma Knife reimbursement rate from approximately $9,900 to $5,300, effective April 1, 2013. This change caused a substantial reduction in the Company’s revenues during 2013 and 2014. Effective January 1, 2015, the Centers for Medicare and Medicaid (CMS) established a Comprehensive Ambulatory Payment Classification for single session radiosurgery treatments, which increased the reimbursement rate from approximately $4,100 to $9,700. The 2016 total CMS reimbursement rate of approximately $8,800 increased to approximately $9,000 in 2017 and will increase to approximately $9,100 in 2018 for a Medicare beneficiary Gamma Knife treatment. The Company’s IGRT services are reimbursed by CMS and other insurers. Reimbursement for these services has remained fairly stable.Knife. See additional discussion under “Item 1A Risk Factors”.

We are unable to predict the effect of future government health care funding policy changes on operations. If the rates paid by governmental payers are reduced, if the scope of services covered by governmental payers is limited, or if one or more of our hospital clients are excluded from participation in the Medicare program or any other government health care program, there could be a material adverse effect on our business.

Affordable Care Act

and Subsequent Regulation

In March 2010, President Obama signed into law the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2010, (“Affordable Care Act”), which has resulted in significant changes to the health care industry. The primary goal of the legislation was to extend health care coverage to approximately 32 million uninsured legal U.S. residents through both an expansion of public programs and reforms to private sector health insurance. According to the National Center for Health Statistics, in 2016 there were 28.6 million uninsured Americans down from more than 48.0 million in 2010. Of those covered by private insurance in 2016, 11.6 million had purchased their plans through federal or state-based exchanges established by the Affordable Care Act. The expansion of insurance coverage iswas expected to be funded in part by measures designed to promote quality and cost efficiency in health care delivery and by budgetary savings in the Medicare and Medicaid programs. Because the Company is not a health care provider, we arewere not directly affected by the law, but we could be indirectly affected principally as follows:

·An increase in the number of insured residents could potentially increase the number of patients seeking Gamma Knife or radiation therapy treatment.

·The Company’s retail contracts are subject to reimbursement rate changes for radiosurgery or radiation therapy services by the government or other third-party payors. Any changes to Medicare or Medicaid reimbursement through the repeal or modification of the Affordable Care Act could affect revenue generated from these sites.

The Company’s retail contracts are subject to reimbursement rate changes for radiosurgery or radiation therapy services by the government or other third-party payors. Any changes to Medicare or Medicaid reimbursement through the repeal or modification of the Affordable Care Act could affect revenue generated from these sites.
Some of the provisions of the Affordable Care Act have yet to be fully implemented, while certain provisions have been subject to judicial and Congressional challenges. While Congress has not passed comprehensive repeal legislation, it has enacted laws that modify certain provisions of the Affordable Care Act such as removing penalties, starting January 1, 2019, for not complying with the Affordable Care Act’s individual mandate to carry health insurance and delaying the implementation of certain Affordable Care Act-mandated fees. On December 14, 2018, a U.S. District Court Judge in the Northern District of Texas, or Texas District Court Judge, ruled that the individual mandate is a critical and inseverable feature of the Affordable Care Act, and therefore, because it was repealed as part of the Tax Cuts and Jobs Act, the remaining provisions of the Affordable Care Act are invalid as well. While the Texas District Court Judge and CMS, have stated that the ruling will have no immediate effect, it is unclear how this decision, subsequent appeals, and other efforts to repeal and replace the Affordable Care Act will impact the Affordable Care Act.
In addition, other legislative changes have been proposed and adopted in the United States since the Affordable Care Act was enacted. On August 2, 2011, the Budget Control Act of 2011, among other things, created measures for spending reductions by Congress. A Joint Select Committee on Deficit Reduction, tasked with recommending a targeted deficit reduction of at least $1.2 trillion for the years 2013 through 2021, was unable to reach required goals, thereby triggering the legislation’s automatic reduction to several government programs. This includes aggregate reductions to Medicare payments to providers of up to 2% per fiscal year, started in April 2013, and, due to subsequent legislative amendments, will stay in effect through 2027 unless additional Congressional action is taken. On January 2, 2013, the then-U.S. President signed into law the American Taxpayer Relief Act of 2012, which, among other things, also reduced Medicare payments to several providers, including hospitals, imaging centers and cancer treatment centers, and increased the statute of limitations period for the government to recover overpayments to providers from three to five years. It is unclear what effect, if any, the shifting legislative and other governmental proposals would have on our business.
GOVERNMENT REGULATION

The payment of remuneration to induce the referral of health care business has been a subject of increasing governmental and regulatory focus in recent years. Section 1128B(b) of the Social Security Act (sometimes referred to as the "federal“federal anti-kickback statute"statute”) provides criminal penalties for individuals or entities that offer, pay, solicit or receive remuneration in order to induce referrals for items or services for which payment may be made under the Medicare and Medicaid programs and certain other government funded programs. The Affordable Care Act amended the anti-kickback statute to eliminate the requirement of actual knowledge, or specific intent to commit a violation, of the anti-kickback statute. The Social Security Act provides authorizes the Office of Inspector General through civil proceedings to exclude an individual or entity from participation in the Medicare and state health programs if it is determined any such party has violated Section 1128B(b) of the Social Security Act. However, the federal anti-kickback statute is subject to evolving interpretations. In the past, the government has enforced the federal anti-kickback statute to reach large settlements with healthcare companies based on sham consulting and other financial arrangements with physicians. A person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation. In addition, the government may assert that a claim including items or services resulting from a violation of the federal anti-kickback statute constitutes a false or fraudulent claim for purposes of the False Claims Act. The Company believes that it is in compliance with the federal anti-kickback statute. Additionally, the majority of states also have anti-kickback laws, which establish similar prohibitions and, in some cases, may apply to items or services reimbursed by any third-party payor, including commercial insurers.

Additionally, the Omnibus Budget Reconciliation Act of 1993, often referred to as "Stark II"“Stark II”, bans physician self-referrals to providers of designated health services with which the physician has a financial relationship. On September 5, 2007, the third and final phase of the Stark regulations (Phase III) was published. The term "designated“designated health services"services” includes, among others, radiation therapy services and in-patient and out-patient hospital services. On January 1, 1995, the Physician Ownership and Referral Act of 1993 became effective in California. This legislation prohibits physician self-referrals for covered goods and services, including radiation oncology, if the physician (or the physician's immediate family) concurrently has a financial interest in the entity receiving the referral. The Company believes that it is in compliance with these rules and regulations.

On August 19, 2008, the CMS published a final rule relating to inpatient hospital services paid under the Inpatient Prospective Payment System for discharges in the Fiscal Year 2009 (the “Final Rule”). Among other things, the Final Rule prohibits “per-click payments” to certain physician lessors for services rendered to patients who were referred by the physician lessor. This prohibition on per-click payments for leased equipment used in the treatment of a patient referred to a hospital lessee by a physician lessor applies regardless of whether the physician himself or herself is the lessor or whether the lessor is an entity in which the referring physician has an ownership or investment interest. The effective date of this prohibition was October 1, 2009. However, referrals made by a radiation oncologist for radiation therapy or ancillary services necessary for, and integral to, the provision of radiation therapy (such as Gamma Knife services) are not subject to this prohibition so long as certain conditions are met. GK Financing’s majority owned subsidiaries, AGKE and JGKE have minority ownership interests that are held solely by radiation oncologists, who are otherwise exempt from the referral prohibition under the Final Rule. The Company believes it is in compliance with the Final Rule.

A range of federal civil and criminal laws target false claims and fraudulent billing activities. One of the most significant is the Federal False Claims Act, which prohibits the submission of a false claim or the making of a false record or statement in order to secure a reimbursement from a government-sponsored program. In recent years, the federal government has launched several initiatives aimed at uncovering practices which violate false claims or fraudulent billing laws. Claims under these laws may be brought either by the government or by private individuals on behalf of the government, through a "whistleblower"“whistleblower” or "qui tam"“qui tam” action. The Company believes that it is in compliance with the Federal False Claims Act; however, because such actions are filed under seal and may remain secret for years, there can be no assurance that the Company or one of its affiliates is not named in a material qui tam action.

Legislation in various jurisdictions requires that health facilities obtain a Certificate of Need ("CON"(“CON”) prior to making expenditures for medical technology in excess of specified amounts. Four of the Company’s existing customers were required to obtain a CON or its equivalent. The CON procedure can be expensive and time consuming and may impact the length of time before Gamma Knife services commence. CON requirements vary from state to state in their application to the operations of both the Company and its customers. In some jurisdictions the Company is required to comply with CON procedures to provide its services and in other jurisdictions customers must comply with CON procedures before using the Company's services. The Company is unable to predict if any jurisdiction will eliminate or alter its CON requirements in a manner that will increase competition and, thereby, affect the Company's competitive position.

The Company's Gamma Knife units contain Cobalt 60 radioactive sources. The medical centers that house the Company's Gamma Knife units are responsible for obtaining possession and user's licenses for the Cobalt 60 source from the Nuclear Regulatory Commission. The Company’s Gamma Knife center in Peru was responsible for obtaining possession and user’s licenses for the Cobalt-60 sources from the Peruvian Regulatory Agencies.

Standard linear accelerator equipment utilized to treat patients is regulated by the FDA. The licensing is obtained by the individual medical center operating the equipment.

The Company believes it is in substantial compliance with the various rules and regulations that affect its businesses.

INSURANCE AND INDEMNIFICATION

The Company's contracts with equipment vendors generally do not contain indemnification provisions. The Company maintains a comprehensive insurance program covering the value of its property and equipment, subject to deductibles, which the Company believes are reasonable.

The Company's customer contracts generally contain mutual indemnification provisions. The Company maintains general and professional liability insurance in the United States. The Company is not involved in the practice of medicine and therefore believes its present insurance coverage and indemnification agreements are adequate for its business. The Company’s Peruvian and Ecuadorian Gamma Knife center is acenters are free-standing facilityfacilities operated by GKPeru. GKPeru’sGKPeru and GKCE, respectively. The treating physicians and clinical staff are these facilities are independent contractors. The Company maintains general and professional liability insurance consistent with the operations of this facilitythese facilities and believes its present coverage is adequate for its business.

Company, Industry and Economic Risk
The Federal Reimbursement RateImpact of the COVID-19 pandemic and associated economic disruptions may continue to adversely affect the company’s business operations and financial condition.
The ongoing novel coronavirus COVID-19 has spread across the globe, has been declared a national emergency in the United States and, during 2020, shut down many business operations around the globe. Many states and municipalities in the United States, including California, have recommended or mandated aggressive and unprecedented actions to reduce the spread of the disease, including limiting non-essential gatherings of people, ceasing all non-essential travel, ordering certain businesses and government agencies to cease non-essential operations at physical locations and issuing shelter-in-place” orders, which direct individuals to shelter at their places of residence (subject to limited exceptions). Across our operations, although most governmental restrictions on certain medical procedures have been lifted, the pandemic adversely impacted our business, as healthcare resources were being prioritized for the treatment and management of the outbreak in some cases. Consequently, there were and continue to be delays in delivering certain Gamma Knife and PBRT treatments and significant volatility or reductions in demand for such treatments may continue. The COVID-19 pandemic poses the risk that the Company or its employees, contractors, customers, government and third party payors and others may be prevented from conducting business activities at full capacity for an indefinite period of time, including due to spread of the disease within these groups or due to shutdowns that have been and may continue to be recommended or mandated by governmental authorities.
A broad, sustained continuation of the COVID-19 pandemic could continue to negatively impact the Company for the following reasons:
operations at certain medical facilities, including medical professionals and other medical facility employees, may be subject to prolonged closure or shut down and may impact our ability to market and deliver Gamma Knife and PBRT treatments;
medical facilities may defer certain Gamma Knife and PBRT treatments for non-urgent patient cases in order to allocate resources to the care of patients with COVID-19;
patients may continue to defer certain Gamma Knife and PBRT treatments due to real or perceived concerns about the potential spread of COVID-19 in a medical facility setting;
certain deferred Gamma Knife and PBRT treatments may not be rescheduled for a later date;
there may be significant volatility or continued reductions in demand for Gamma Knife Treatments Has Fluctuated

and PBRT treatments due to limitations on operations at medical facilities, including in geographies that continue to experience severe impacts of the pandemic;

the pandemic may materially impact the Company’s operations for a sustained period of time due to the current travel bans and restrictions, quarantines, shelter-in-place orders and shutdowns, including at our corporate headquarters in San Francisco, California;
and/or members of the board, management or employee team, some of whom are particularly at risk for the severe symptoms of COVID-19, or of our small number of other employees, may become ill or have family members who are ill and are absent as a result, or they may elect not to come to work due to the illness affecting others in our office or facilities.

The occurrence of any of the foregoing events could have a material adverse effect on our business, results of operations, financial condition, liquidity and cash flows. The COVID-19 pandemic and mitigation measures have had and may continue to have an adverse impact on global economic conditions and healthcare activity, which could have an adverse effect on the Company’s business and financial condition. The full impact of the COVID-19 pandemic remains unknown, including the impact on the global economy and the healthcare industry. The extent to which the COVID-19 outbreak impacts the Company’s results will depend on future developments that are highly uncertain and cannot be predicted, including new information that may emerge concerning the severity of the virus, the effectiveness and implementation of vaccinations to counter the virus, actions to contain its impact, the efficacy of the current governmental orders in slowing down the pandemic, the governments’ changing calculations on the economic impact and the health implications of maintaining these orders, the progress in the healthcare industry’s ability to effectively combat the virus, and potential increase or decrease in healthcare demand, volatility and uncertainty resulting from COVID-19 responses, all of which are highly unpredictable. Likewise, the financial market as a whole has experienced extreme volatility as a result of the global economic impact of the COVID-19 pandemic, which has impacted, and may continue to impact, the Company’s stock price.

We refer you to “Management’s Discussion and Analysis of Financial Position and Results of Operations” for a more detailed discussions of the potential impact of the COVID-19 pandemic and associated economic disruptions, and the actual operational and financial impacts that we have experienced to date.

If the Company is not successful at diversifying its business model, its revenues and profitability may decline.

The Company has historically relied on Gamma Knife unit placement and a PBRT system to provide its revenues. Currently, there is a limited market for Gamma Knife equipment and there are few prospects for PBRT systems. As a result, we plan to adapt our business model to place other types of stereotactic radiosurgery and advanced radiation therapy equipment in addition to Gamma Knife units and PBRT systems. This will constitute a reorientation for the Company and there can be no assurance that we can successfully adapt our historical business model to these new product offerings. If we are not successful, our revenues and profitability could decline substantially as existing contracts expire and are not renewed.

The Federal reimbursement rate for Gamma Knife treatments may not provide the Company with an adequate return on its investment.

Congress enacted legislation in 2013 that significantly reduced the Medicare reimbursement rate for outpatient Gamma Knife treatment by setting it at the same amount paid for linear accelerator-based radiosurgery treatment. Prior to April 1, 2013, Medicare’s reimbursement rate for Gamma Knife treatment hadhas been relatively stable. In April 2013,stable during the Medicare reimbursement rate for Gamma Knife treatment was lowered from approximately $9,900 to $5,300 per treatment session. This sudden reduction in a rate that had historically been stable resulted in a significant decrease in the Company’s revenues from all of our revenue sharing and some of our fixed fee medical centers. The reimbursement rate was subsequently increased to approximately $5,600 in 2014. Effective January 1, 2015, CMS established a comprehensive Ambulatory Payment Classification (APC) for both Gamma Knife and LINAC one session cranial radiosurgery at a reimbursement rate of approximately $9,700. This represents an estimated increase of $4,100 per Medicare Gamma Knife treatment (exclusive of co-insurance and other adjustments) effective January 1, 2015 compared to the 2014 Medicare reimbursement rate. The 2016 reimbursement level was reduced by CMS to approximately $8,800 but increased to approximately $9,000 in 2017 and increased again to $9,100 in 2018.last five years. There can be no assurance that CMS reimbursement levels will be maintained at levels providing the Company an adequate return on its investment. Any future reductions in the reimbursement rate would adversely affect the Company’s revenues and financial results.


Introduction of the RO APM Reimbursement Model.

On September 18, 2020, CMS issued the final rule that would implement a new mandatory payment model for radiation oncology services: the Radiation Oncology Alternative Payment Model (“RO APM”). The averageRO APM is scheduled to commence January 1, 2022 and will be in effect for a five (5) year period. The RO APM significantly alters CMS' payment methodology from a fee for service paradigm to a set reimbursement by cancer type methodology for radiation services provided within a 90 day episode of care. Under the RO APM, hospital based and free-standing radiation therapy providers are mandatorily required to participate in the model based on whether the radiation therapy provider is located within a randomly selected Core Based Statistical Area ("CBSA"). CMS projects that providers treating approximately 30% of radiation oncology patients have been selected to participate in the RO APM. The remaining providers not included in the RO APM will continue to receive reimbursement based on a fee-for-service methodology. The RO APM includes but is not limited to PBRT and Gamma Knife services. Four (4) of the Company's Gamma Knife centers are scheduled to be included in the RO APM. It is not anticipated that inclusion in the RO APM will have a significant impact on the Company's Gamma Knife revenues. The Company's PBRT center was not selected for inclusion in the RO APM. For centers not included in the RO APM proposed model, Medicare reimbursement rate trends from 2014 to 2018 are outlined below:

Average Medicare Reimbursement Rate Trends

2014  2015  2016  2017  2018 
$5,600  $9,700  $8,800  $9,000  $9,100 

in 2021 for the most commonly used PBRT delivery codes will increase by approximately 4.1% and decrease by approximately 1.7% for Gamma Knife.

In some cases, we contribute additional funds for capital costs and/or annual operating and equipment related costs such as marketing, maintenance, insurance and property taxes. Due to the structure of our contracts with medical centers, there can be no assurance that these costs will be fully recovered or that we will earn a satisfactory return on our investment.

limited and the Company may not be able to place additional Gamma Knife units which could negatively impact the Company's revenue and financial results.

There is a limited market for the Gamma Knife, and the market in the United States may be mature. The Company has begun and continued operation at only nine (9)seven (7) new Gamma Knife sites in the United States since 2011. Due to the substantial costs of acquiring a Gamma Knife unit, we must identify medical centers that possess neurosurgery and radiation oncology departments capable of performing a large number of Gamma Knife procedures. As of December 31, 2017,2020, there were approximately 118116 operating Gamma Knife units in the United States, of which sixteen (16)fourteen (14) units were owned by the Company. As of December 31, 2017, the Company has one idle Gamma Knife unit with a cumulative net book value of $729,000. There are currently no plans to place into service or trade this unit in during 2018. There can be no assurance that we will be successful in placing these idle units or additional units at any sites in the future. The Company’s existing contracts with its customers are fixed in length and there can be no assurance that the customers will wish to extend the contract beyond the end of the term.

The Company’s business is capital intensive. The Company finances its Gamma Knife units through its GKF subsidiary. The amounts financed through GKF have been generally non-recourse to ASHS. The Company financed its first proton therapy unit through its wholly-owned subsidiary, Orlando, and guaranteed the lease financing. The Company’s combined long-term debt and capitalfinance leases totaled $23,143,000$13,516,000 as of December 31, 20172020 and is collateralized by its Gamma Knife, MEVION S250 and other assets, including accounts receivable and future proceeds from any contract between the Company and any end user of the financed equipment. This highDepending on the Company’s financing requirements and market conditions, the Company may seek to finance its operations by incurring additional long-term debt in the future. The Company’s current level of debt may adversely affect the Company’s ability to secure additional credit in the future, and as a result may affect operations and profitability. If a default on debt occurs in the future, the Company’s creditors would have the ability to accelerate the defaulted loan, to seize the Gamma Knife or MEVION S250 units or other equipment with respect to which default has occurred, and to apply any collateral they may have at the time to cure the default.

A limited number of customers have historically accounted for a substantial portion of the Company’s total revenue, and the Company expects such customer concentration to continue for the foreseeable future. For example, in 2017, five (5)2020, four (4) customers in total accounted for more thanapproximately 50% of the Company’s revenue.

The Company estimates that there are two other companies that actively provide alternative, non-conventional Gamma Knife financing to potential customers. We believe there are no competitor companies that currently have more than three (3) Gamma Knife units in operation. The Company’s relationship with Elekta, the manufacturer of the Leksell Gamma Knife unit, is non-exclusive, and in the past the Company has lost sales to customers that chose to purchase a Gamma Knife unit directly from Elekta. The Company also has several competitors in the financing of proton therapy projects. The Company’s business model differs from its competitors, but there can be no assurances that the Company will not lose placements to its competitors. In addition, the Company may continue to lose future sales to customers purchasing equipment directly from manufacturers. There can be no assurance that the Company will be able to successfully compete against others in placing future units.

Other radiosurgery devices and conventional neurosurgery compete against the Gamma Knife. Each of the medical centers targeted by the Company could decide to acquire another radiosurgery device instead of a Gamma Knife.Knife to perform cranial radiosurgery. In addition, neurosurgeons who are responsible for referring patients for Gamma Knife surgery may not be willing to make such referrals for various reasons, instead opting for invasive surgery. ThereBecause of these competing technologies, there can be no assurance that the Company will be able to secure a sufficient number of future sites or Gamma Knife procedures to sustain its profitability and growth.

The Company installed a Gamma Knife unit in Lima, Peru in 2017.2017 and acquired a Gamma Knife unit operation in Guayaquil, Ecuador in 2020. International operations can be subject to exchange rate volatility, which could have an adverse effect on our financial results and cash flows. In addition, international operations can be subject to legal and regulatory uncertainty and political and economic instability, which could result in problems asserting property or contractual rights, potential tariffs, increased compliance costs, increased regulatory scrutiny, potential adverse tax consequences, the inability to repatriate funds to the United States, and the Company’s inability to operate in those locations.

New Technologytechnology and Products Could Resultproducts could result in Equipment Obsolescence 

making the Company's equipment obsolete which could have a material adverse impact on its business and results of operations.

There is constant change and innovation in the market for highly sophisticated medical equipment. New and improved medical equipment can be introduced that could make the Gamma Knife technology obsolete and that would make it uneconomical to operate. During 2000, Elekta introduced an upgraded Gamma Knife which cost approximately $3.6 million plus applicable tax and duties. This upgrade includes an Automatic Positioning System™ (“APS”), and therefore involved less health care provider intervention. In early 2005, Elekta introduced a new upgrade, the Gamma Knife Model 4C (“Model 4C”). The cost to upgrade existing units to the Model 4C with APS was approximately $200,000 to $1,000,000, depending on the current Gamma Knife configuration. In 2006 Elekta introduced a new model of the Gamma Knife, the Perfexion, which costs approximately $4.5 million plus applicable taxes and duties.the Company has implemented at all of its domestic sites. The Perfexion can perform procedures faster than previous Gamma Knife models and it involves less health care personnel intervention. In 2015, Elekta introduced the Leksell Gamma Knife IconTM. The Perfexion is upgradeable to the Icon platforms which has enhanced imaging capabilities allowing for treatment without a head frame and the treatment of larger tumors. Existing model 4Cs of the Gamma Knife are not upgradeable to the Perfexion model. As of March 1, 2018, 14 of2021, all the Company’s Gamma Knife units in the United States are Perfexion models; of the Company’s remaining Gamma Knife units,models and two (2) areof these Perfexion units have the Icon upgrade. The Company's two (2) South American sites utilize the Model 4Cs with APS and one is upgradeable to a more advanced Model 4C unit.4(C). The failure to acquire or use new technology and products could have a material adverse effect on our business and results of operations.

In addition, there are constant advances made in radiation therapy equipment.


The Company purchased IGRT and CT Simulator systems in 2006 with a list price of approximately $8,300,000. As in the Gamma Knife business, new and improved IGRT equipment can be introduced that could make the existing technology obsolete and that would make it uneconomical to operate.

We have committed a substantial amount of our financial resources to next-generation proton beam technology. The first MEVION S250 system began treating patients in December 2013. The Company’s first MEVION S250 system began treating patients in April 2016. The Company has committed to purchase two (2) additional MEVION S250S250i systems and has already made deposits of $2,000,000$2,250,000 towards this commitment. There can be no assurance that we will be able to obtain additional customers or be able to finance the two additional systems.

If we are unable to obtain additional customers or are unable to finance the two additional systems, the Company will lose its deposits and there may be a negative impact on the Company’s business and results of operations.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The COVID-19 pandemic, the resulting recession in the United States and its follow-on effects have impacted and will likely continue to impact business activity across industries, including the Company’s. During 2020, due to factors related to the COVID-19 pandemic such as delays in service at medical facilities and restrictions imposed by government agencies, and the Company’s customers in response to the spread of COVID-19, the Company experienced some delays in delivering certain Gamma Knife procedures and PBRT treatments. Similarly, the Company’s ability to conduct commercial efforts with its customers have been and are likely to continue to be disrupted as customers have turned their focus to dealing with the impact of the COVID-19 pandemic on their operations and have restricted access to their sites in efforts to contain the spread of the virus. The global nature of the pandemic has resulted in authorities implementing numerous measures designed to contain the virus, including travel bans and restrictions, border closures, quarantines, shelter-in-place orders, business limitations and shutdowns. The impact of the COVID-19 pandemic on the global economy and capital markets is significant, and on June 8, 2020 the National Bureau of Economic Research announced that the United States was in an economic recession. An extended economic recession in the United States or elsewhere could have a material adverse effect on the Company’s ability to conduct its business and to access financing, as well as on the Company’s results of operation, financial condition, liquidity and cash flows. The prioritization of COVID-19 treatment and containment has resulted in delays in decisions by the Company’s customers and their patients, obstacles to the Company’s ability to market and deliver its services, declines in treatment volumes and adverse impacts to revenues for both Gamma Knife procedures and PBRT treatments. As a result of the pandemic and related governmental actions, Gamma Knife procedures and PBRT treatments, which currently make up all of the Company’s revenue, may be impacted differently at each of the Company’s various locations and may take longer to recover than other areas of the economy, which may have a material impact on the Company's business. The Company’s Gamma Knife operations in Latin America have experienced a decline in procedures due to the COVID-19 pandemic. Our Gamma Knife and PBRT operations in the United States have also experienced negative impacts from the COVID-19 pandemic. As the COVID-19 pandemic continues to develop, additional impacts may arise that we are not aware of currently.

Table of Contents
The impact of the COVID-19 pandemic for the year ended December 31, 2020 has varied by location based on the stage of containment and actions by government agencies. The impact on treatments and costs in the three-month period ended March 31, 2020 did not appear material. The impact of the COVID-19 pandemic has been greater for the three-month periods ended June 30, 2020, September 30, 2020, and December 31, 2020, including declines in patient volumes and corresponding reductions in Gamma Knife procedures and reduced PBRT fractions during the second and fourth quarters.
APPLICATION OF CRITICAL ACCOUNTING POLICIES

The Company’s consolidated financial statements are prepared in accordance with generally accepted accounting principles and follow general practices within the industry in which it operates. Application of these principles requires management to make estimates, assumptions and judgments that affect the amounts reported in the financial statements and accompanying notes. These estimates, assumptions and judgments are based on information available as of the date of the financial statements; accordingly, as this information changes, the financial statements could reflect different estimates, assumptions and judgments. Certain policies inherently have a greater reliance on the use of estimates, assumptions and judgments and as such have a greater possibility of producing results that could be materially different than originally reported.

The most significant accounting policies followed by the Company are presented in Note 2 to the consolidated financial statements. These policies along with the disclosures presented in the other financial statement notes and, in this discussion, and analysis, provide information on how significant assets and liabilities are valued in the financial statements and how those values are determined. Based on the valuation techniques used and the sensitivity of financial statement amounts, and the methods, assumptions and estimates underlying those amounts, management has identified revenue recognition and costs of sales for turn-key and revenue sharing arrangements, and the carrying value of fixed assets and useful lives, and the carrying value of its Mevion investment to be the areas that required the most subjective or complex judgments, and as such could be most subject to revision as new information becomes available. The following are our critical accounting policies in which management’s estimates, assumptions and judgments most directly and materially affect the financial statements:

Revenue Recognition

The Company has one revenue-generating activity, which consists of equipment leasing to hospitals,recognizes revenues under Accounting Standards Codification (“ASC”) 842 Leases (“ASC 842”) and includes the operation ofASC 606 Revenue from Contracts with Customers (“ASC 606”). The Company had sixteen (16) Gamma Knife units byand one (1) PBRT system in operation as of December 31, 2020. Four (4) of the Company’s customer contracts are through subsidiaries where GKF or its subsidiary is the operationmajority owner and managing partner. Six (6) of one proton therapy unit bythe Company’s sixteen (16) current Gamma Knife customers are under fee-per-use contracts, and eight (8) customers are under retail arrangements. The Company, through GKF, also owns and operates single-unit Gamma Knife facilities in Lima, Peru and Guayaquil, Ecuador. These units economically function similar to the Company’s turn-key retail arrangements. The Company’s PBRT system at Orlando and the operation of one IGRT site by ASHS.

RevenueHealth – UF Health Cancer Center (“Orlando Health”), is recognizedalso considered a retail arrangement.

Rental Income from Medical Services
The Company recognizes revenues under ASC 842 when services have been rendered and collectability is reasonably assured, on either a fee per use or revenue sharing basis. During 2017, the Company had ten (10) fee per use arrangements and ten(10) retail service arrangements. Under both of these types of agreements, the hospital is responsible for billing patients and collecting technical component fees for services performed. Revenue associated with installationThe terms of the Gamma Knife, PBRT, and IGRT units, ifcontracts do not contain any is a part of the negotiated lease amount and not a distinctly identifiable amount.guaranteed minimum payments. The costs, if any, associated with installation of the units are amortized over the period of the related lease to match revenue recognition of these costs.

For fee per use agreements, revenue is not estimated because theseCompany’s contracts provide for a fixed fee per procedure and are typically for a ten-year term. Revenueterm and are classified as either fee per use or retail. Retail arrangements are further classified as either turn-key or revenue sharing. Revenues from fee per use contracts is determined by each hospital’s contracted rate. Revenues are recognized at the time the procedures are performed, based on each hospital’s contracted rate. There is no guaranteed minimum payment. Costs related to operatingrate and the units are charged to costsnumber of operations as incurred, which approximatesprocedures performed. Under revenue sharing arrangements, the recognitionCompany receives a contracted percentage of the related revenue. Revenue under fee per use agreementsreimbursement received by the hospital. The amount the Company expects to receive is recorded in accordance withas revenue and estimated based on historical experience. Revenue estimates are reviewed periodically and adjusted as necessary. Under turn-key arrangements, the contract terms.

During 2017, ASHS had one (1) agreement, Orlando had one (1) agreement, and GKF had eight (8) agreements that are retail service arrangements. These can be further classified as either “turn-key” arrangements or “revenue sharing” arrangements. For GKF’s five (5) turn-key sites, GKF is solely responsible for the costs to acquire and install the Gamma Knife. In return, GKFCompany receives payment from the hospital in the amount of itsthe hospital’s reimbursement from third party payors. Revenue is recognized bypayors, and the Company duringis responsible for paying all the period in whichoperating costs of the procedure is performed and is estimatedequipment. Operating costs are determined primarily based on what can be reasonably expected to be paid by the third-party payor tohistorical treatment protocols and cost schedules with the hospital. The Company records an estimate is primarily determined from historical experience and hospital contracts with third party payors. These estimatesof operating costs which are reviewed on a regular basis and adjusted as necessary to more accurately reflect the expected payment amount. The Company also records an estimate ofactual operating costs associated with each procedure during the period in which the procedure is performed.costs. For two of the turn-key sites, the Company also shares a percentage of net operating profit. The Company records an estimate of net operating profit based on estimated revenues, less estimated operating costs. Costs are determined primarily based on historical treatment protocols and cost schedules with the hospital. The Company’s estimated operating costs and estimated net operating profit are reviewed on a regular basisrecorded as other direct operating costs in the consolidated statement of operations. As of December 31, 2020 and adjusted as necessary to more accurately reflect the actual operating costs. Revenue for turn-key sites is recorded on a gross basis, and the operating expenses2019, the Company reimburses to the hospital are recorded in other operating costs.

recognized revenues of approximately $16,204,000 and $19,396,000 under ASC 842, respectively.

Under revenue sharing arrangements the hospital shares in the responsibility and risk with the Company for the capital investment to acquire and install the equipment. Unlike our turn-key arrangement, the lease payment under a revenue sharing arrangement is a percentage of reimbursed revenue. Payments are made by the hospital, generally on a monthly basis, to the Company based on an agreed upon percentage allocation of cash collected. Revenue is recognized during the period in which procedures are performed and is estimated based on the reimbursement amount that the Company expects to receive from the hospital for those procedures. This estimate is reviewed on a regular basis and adjusted as necessary to more accurately reflect the expected payment amount.

Revenue from retail arrangements amounted to approximately 64%, 57% and 47%64% of total revenue for the years ended December 31, 2017, 20162020 and 2015,2019, respectively. Because the revenue estimates are reviewed on a quarterly basis, any adjustments required for past revenue estimates would result in an increase or reduction in revenue during the current quarterly period.

Income tax expense decreased $2,046,000 and increased $509,000 in 2017 and 2016 compared to 2017 and 2016, respectively. On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the "Tax Act"). The Tax Act makes broad and complex changes to the U.S. tax code that affect fiscal 2017, including, but not limited to requiring a one-time transition tax on certain unrepatriated earnings of foreign subsidiaries that is payable over eight years. The Tax Act also establishes new tax laws that will affect 2018 and later years, including, but not limited to, a reduction of the U.S. federal corporate tax rate from 34% to 21%, a general elimination of U.S. federal income taxes on dividends from foreign subsidiaries, net operating loss deduction limitations, a base erosion, anti-tax abuse tax and a deduction for foreign-derived intangible income and a new provision designed to tax global intangible low-taxed income. As these provisions do not apply until 2018 the Company continues to evaluate the impact of such provisions of the Tax Act. As a result of the Tax Act, the Company revalued its federal and state deferred tax liabilities based on a 21% tax rate as opposed to a 34% tax rate. The net effect of this change on the Company’s income tax provision for the year ended December 31, 2017 was a tax benefit of $1,546,000.

The increase in 2016 is due to income from the PBRT system and operations of the Company’s subsidiaries. The loss incurred on the write-down of the Company’s investment in equity securities is a capital loss which is treated as non-deducible expense for income tax provision purposes and as such, a full valuation allowance was recorded against this loss and the net impact to the provision was $0.

The Company anticipates that it will continue to record income tax expense if it operates profitably in the future. Currently there are state income tax payments required for most states in which the Company operates. However, there are minimal current federal income tax payments required due to net operating loss carryforwards and other deferred tax assets available for federal tax purposes.

TheAt December 31, 2020, the Company had aexhausted the remainder of its net operating loss carryforward for federal income tax return purposes at December 31, 2017purposes. The Company has net operating loss carryforwards for state income tax purposes.

This increase was due to the new PBRT system which began operations in April 2016.

IMPAIRMENT ANALYSIS OF INVESTMENT IN EQUITY SECURITIES

As of December 31, 2017, and December 31, 2016 the Company had a $0 and $579,000 investment in the common stock of Mevion, respectively, representing an approximate 0.46% interest in Mevion. The Company accounts for this investment under the cost method. The Company carries its investment in Mevion at cost and reviews it for impairment on a quarterly basis, or as events or circumstances might indicate that the carrying value of the investment may not be recoverable.

Based on guidance provided in Accounting Standards Codification (“ASC”) 320 Investments–Debt and Equity Securities (“ASC 320”) and Staff Accounting Bulletins (“SAB”) Topic 5M Other Than Temporary Impairment (“OTTI”) of Certain Investments in Equity Securities (“SAB Topic 5M”), the Company analyzed the related events of Mevion, that occurred in the second and third quarters of 2015 and its impact on the Company’s investment. The Company determined that these circumstances indicated a decline in value of its Mevion investment that was other-than-temporary and concluded that a write-down of the carrying value should be recognized. As of June 30, 2015, the Company adjusted its investment in Mevion to the estimated fair value of $600,000 and recorded a $2,114,000 impairment loss. The $2,114,000 other than temporary impairment of its investment in Mevion is recorded in other income (loss) on the Company’s Condensed Consolidated Statement of Operations.

During the period ended December 31, 2015, the Company engaged a third-party expert to review and corroborate its assessment of the fair value of the Mevion investment. Based on the third-party analysis, an additional impairment loss of $26,000 was recognized by the Company during the three months ended December 31, 2015. The fair value of the Company’s investment in Mevion, as of December 31, 2015 was approximately $579,000. The impairment loss for the year ended December 31, 2015 was $2,140,000.

During the year ended December 31, 2017, the Company reviewed its investment in Mevion and determined the fair value of its investment was $0. Based on the Company’s assessment of its investment in Mevion, the Company recognized an impairment loss for the year then ended December 31, 2017 of $579,000.

DSO can and does fluctuate depending on timing of customer payments received and the mix of fee per use versus retail customers. Retail sites generally have longer collection periods than fee per use sites.

The Company believes that its cash flow from cash on hand, operations, and other cash resources are adequate to meet its scheduled debt and capitalfinance lease obligations during the next 12 months. See additional discussion below related to commitments.

The Company, in the past, has secured financing for its Gamma Knife and radiation therapy units. The Company has secured financing for its projects from several lenders and anticipates that it will be able to secure financing on future projects from these or other lending sources, but there can be no assurance that financing will continue to be available on acceptable terms.

IMPACT OF INFLATION AND CHANGING PRICES

The Company does not believe that inflation has had a significant impact on operations because a substantial majority of the costs that it incurs under its customer contracts are fixed through the term of the contract.

The non-refundable deposits are recorded in the Condensed Consolidated Balance Sheets as deposits and construction in progress.

On July 21, 2017, the Company signed First Amendments to two System Build Agreements (the “Amendments”) for the Company’s second and third Mevion PBRT units. The Company and Mevion have agreed on preliminary construction and delivery timetables for the second and third PBRT units for which the Company has purchase commitments. The Company’s delivery timeframe is triggered by USFDA 510K clearance of Mevion’s recently developed treatment nozzle. The Company is actively seeking sites for these units but, to date, has not entered into agreements with any party for either placement of a PBRT unit or the related financing. The Company projects that it will be required to take delivery of the second and third PBRT units no later than 2019 and 2020, respectively.

On July 21, 2017, the Company entered into a Maintenance and Support Agreement (the “Mevion Service Agreement”) with Mevion, which provides for maintenance and support of the Company’s PBRT unit at Orlando Health. The Mevion Service Agreement began September 5, 2017 and required an upfront payment of $1,000,000 which was made on August 4, 2017, and further requires payments over the next 11 months. This payment portion was recorded as a prepaid contract and will be amortized over the one-year service period. The Mevion Service Agreement is for a five (5) year period.

As of December 31, 2017, the Company had commitments to perform two Cobtalt-60 reloads at existing Gamma Knife customer sites. Total Gamma Knife commitments as of December 31, 2017 were $1,500,000.

ITEM 9A. CONTROLS AND PROCEDURES

(a)Evaluation of disclosure controls and procedures.

(a)Evaluation of disclosure controls and procedures.
Our Chief Executive Officer and our Chief Financial Officer, after evaluating the effectiveness of the Company’s “disclosure controls and procedures” (as defined in the Securities Exchange Act of 1934 (“Exchange Act”) Rules 13a-15(e) and 15d-15(e)) as of the end of the period covered by this annual report, have concluded that our disclosure controls and procedures are effective based on their evaluation of these controls and procedures required by paragraph (b) of Exchange Act Rules 13a-15 or 15d-15.

(b)Management’s report on internal control over financial reporting.

(b)Management’s report on internal control over financial reporting.
The management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting. The Company’s internal control system was designed to provide reasonable assurance to its management and Board of Directors regarding the preparation and fair presentation of published financial statements.

28

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

Management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2017.2020. In making this assessment, it used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control – Integrated Framework (2013). Based on this assessment management believes that, as of December 31, 2017,2020, the Company’s internal control over financial reporting is effective based on those criteria.

(c)Changes in internal controls over financial reporting.

In June 2020, the Company acquired Gamma Knife Center Ecuador S.A. (“GKCE”). Management excluded GKCE from its report on internal controls over financial reporting as of December 31, 2020. GKCE's financial statements constitute 3.8% and 3.6% of the Company’s consolidated total assets (excluding $1,343,000 of goodwill and intangible assets and $19,000 of land, which were integrated into the Company’s control environment), and revenues, respectively. The Company will include GKCE in its assessment of the effectiveness of internal controls over financial reporting in fiscal year 2021 annual management report, the annual management report following the first anniversary of the acquisition.

Report of Independent Registered Public Accounting Firm

To the StockholdersShareholders and the Board of Directors of

American Shared Hospital Services, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of American Shared Hospital Services, Inc. (the “Company”) as of December 31, 20172020 and 2016,2019, and the related consolidated statements of operations, stockholders’shareholders’ equity and cash flows for the three years then ended, December 31, 2017.and the related notes. In our opinion, the consolidated financial statements present fairly, in all material respects, the consolidated financial position of the Company as of December 31, 20172020 and 2016,2019, and the consolidated results of its operations and its cash flows for the three years then ended, December 31, 2017, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB��PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.


We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit auditswe are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.


Our auditsincluded performing procedures to assess the risks of material misstatement of the consolidatedfinancial statements, whether due to error or fraud, and performing procedures to respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.


Critical Audit Matters
The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which they relate.

Retail Revenue Recognition – Estimates of Reimbursement Rates and Payor Mix
As discussed in Note 2 in the Company’s consolidated financial statements, retail revenue amounted to approximately $11,418,000, which was approximately 64% of total consolidated revenue, during the year ended December 31, 2020. The related accounts receivable balance for total retail sites accounted for 68% of total accounts receivable at December 31, 2020. The Company has retail customer revenue classified as either turn-key or revenue sharing that are recognized under Accounting Standards Codification (“ASC”) 842 Leases (“ASC 842”). Under revenue sharing arrangements, the Company receives a contracted percentage of the reimbursement received by the hospital. Under turn-key arrangements, the Company receives payment from the hospital based on the amount of the hospital’s reimbursement from third party payors.

We identified management’s estimates of reimbursement rates and payor mix to record retail revenue and related accounts receivable, as a critical audit matter. Retail revenue and related accounts receivable involves significant judgment and estimation, including measurement uncertainty, by management based on the estimates and assumptions used and are subject to adjustments based on actual reimbursements received by the Company. In turn, auditing management’s judgments and estimates related to retail revenue and related accounts receivable involved a high degree of subjectivity, as they are based on estimates of reimbursement rates and payor mix.

The primary procedures we performed to address this critical audit matter included:

a.Obtaining management’s reconciliation of retail revenue and accounts receivable by site agreeing to supporting documentation related to the estimated reimbursement rates and payor mix used in the calculation.
F- 3

Table of Contents

a.Obtaining third party confirmations, confirming number of procedures, payment dates and amounts paid, and reconciling confirmed amounts to management’s reconciliation, in order to validate approximate rate per procedure.

a.Testing subsequent cash receipts and evaluating the reasonableness of the estimates through a look-back analysis over retail revenue as compared to accounts receivable balances previously recognized.

a.Developing an independent expectation of reimbursement rates per procedure based on historical trends, procedures, and payment amounts received through confirmation directly with the hospital, and comparing to management’s estimates.

Property and Equipment - Salvage Value on Equipment
As described in Note 2 to the consolidated financial statements, property and equipment are stated at cost less accumulated depreciation. Depreciation for Gamma Knife, and other equipment is determined using the straight-line method over the estimated useful lives of the assets, which for medical and office equipment is generally 3 – 10 years, and after accounting for salvage value on the equipment where indicated. Salvage value is based on the estimated fair value of the equipment at the end of its useful life.

We identified management’s estimates of salvage value including qualitative assessments of certain equipment as a critical audit matter. Determination of salvage values involves significant judgment and estimation, involving measurement uncertainty, as there is no active resale market for the Gamma Knife units due to limited sellers and buyers and trade-ins for the equipment are not guaranteed. Trade-ins are highly dependent on future demand, values and the Company’s relationship with supplier, a related party of the Company. In turn, auditing management’s judgments and estimates related to salvage value of certain equipment, involved a high degree of subjectivity.

The primary procedure we performed to address this critical audit matter included:
a.Evaluating management’s determination of salvage values by comparing determined salvages values with historical trade-in transactions and publicly available transaction information, which included reviewing relevant purchase agreements, supplier agreements and evaluating publicly available transaction information.

Valuation of Certain Tangible and Intangible Assets Acquired Through Business Combination
As described in Note 4 to the consolidated financial statements, the Company completed the acquisition of Gamma Knife Center Ecuador S.A. (“GKCE”) from GKCE’s selling majority shareholders in June 2020. The Company subsequently executed agreements to acquire 1.3% of the total outstanding shares in July 2020 and intends to acquire the remaining 0.7% at later date. The total purchase consideration for 100% of the outstanding shares of GKCE was approximately $2,869,000, including a base purchase price of $2,000,000, subject to certain price adjustments for current assets and liabilities and tax withholding. The transaction was accounted for as a business combination using the acquisition method, whereby the total consideration transferred, identifiable assets acquired, and liabilities assumed are based on the respective acquisition-date fair values.

As part of the acquisition, the Company acquired tangible assets, including building, equipment and other property and equipment with a fair value of approximately $723,000 and intangible assets, consisting of the acquired entity’s trade name, with a fair value of approximately $78,000. We identified the judgment and estimation of the methodologies and assumptions used in the valuation by management, in the determination of the fair value of these assets, as a critical audit matter. Significant assumptions used to estimate the fair value of these tangible and intangible assets included discount rates, useful lives, expected future cash flows, internal rate of return, revenue forecast and growth rates. Given these factors, the related audit effort in evaluating management’s estimates required a high degree of auditor judgment.

The primary procedures we performed to address this critical audit matter included:

a.Evaluating the appropriateness of the methodologies and assumptions used to estimate the fair value of certain tangible (real property and equipment) and intangible (trade name) assets, including involving valuation specialists, where specialized skill or knowledge was needed, to assist with our evaluation. Our valuation specialist assisted primarily in the evaluation of the qualification of the appraiser and valuation specialist used by management, consideration of methodologies used in the appraisal of real property, including review of market information utilized to determine fair value, and in relation to the valuation of trade name, review of the methodology, discount rate, royalty rate, useful life (indefinite), and internal rate of return.

F- 4

Table of Contents
a.Evaluating assumptions and inputs used in projected financial information of the acquired entity, which primarily related to revenue growth rates, including testing the completeness and accuracy of the underlying data supporting the significant assumptions and estimates. Specifically, when evaluating the assumptions related to the revenue growth rates and changes in the business that would drive these forecasted growth rates, we compared the assumptions to industry trends and subsequent interim period results to evaluate management’s estimates as of the date of the transaction.

Significant accounting estimates reflected in the Company’s consolidated financial statements include the estimated useful lives of fixed assets and its salvage values, revenues and costs of sales for turn-key and revenue sharing arrangements, and the carrying value of its Mevion investment.arrangements.  Actual results could differ from those estimates.

Depreciation for PBRT property and equipment. Depreciationrelated equipment is determined using the modified units of production method, which is a function of both time and usage of the equipment. This depreciation method allocates costs considering the projected volume of usage through the useful life of the PBRT unit, which has been estimated at 20 years. The estimated useful life of the PBRT unit is consistent with the estimated economic life of 20 years.

The Company capitalizes interest incurred on property and equipment that is under construction, for which deposits or progress payments have been made. When a rate is not readily available, imputed interest is calculated using the Company’s incremental borrowing rate. The interest capitalized for property and equipment is the portion of interest cost incurred during the acquisition periods that could have been avoided if expenditures for the equipment had not been made. The Company capitalized interest of $138,000, $443,000,$119,000 and $431,000$110,000 in 2017, 2016,2020 and 2015,2019, respectively, as costs of medical equipment.

The Company leases Gamma Knife and radiation therapy equipment to its customers under arrangements typically accounted for as operating leases. At December 31, 2017,2020, the Company held equipment under operating lease contracts with customers with an original cost of $95,923,000$75,241,000 and accumulated depreciation of $51,403,000.$45,416,000. At December 31, 2016,2019, the Company held equipment under operating lease contracts with customers with an original cost of $96,270,000$92,135,000 and accumulated depreciation of $53,306,000.

In April 2017, an existing customer exercised their option to purchase the Gamma Knife unit at its hospital at the end of the lease term for a predetermined purchase price, pursuant to the lease agreement. The lease terminated in April 2017, at which time, the unit was depreciated to the purchase price of the sale. Based on the guidance provided in ASC 360 Property, Plant and Equipment (“ASC 360”), the Company did not classify or measure the asset as held for sale prior to the lease termination, because the Gamma Knife unit was not available for immediate sale.

Investment in equity securities –As of December 31, 20172020, the Company had common stock representing an approximate 0.46% interest in Mevion Medical Systems, Inc. (“Mevion”),recognized a loss on the write down of impaired assets of $8,264,000. The impaired assets included six (6) Gamma Knife units and accounts for this investmentthe Company's deposits towards purchase of proton beam systems and related capitalized interest. See further discussion under the cost method. The carrying value of the Company’s investment in Mevion was $0 at December 31, 2017. The carrying value of the Company’s investment in Mevion was $579,000 as of December 31, 2016. The Company reviews its investment in Mevion forNote 2 - Long-lived asset impairment on a quarterly basis, or as events or circumstances might indicate that the carrying value of the investment may not be recoverable.

discussion.

Fair value of financial instruments – The Company’s disclosures of the fair value of financial instruments is based on a fair value hierarchy which prioritizes the inputs to the valuation techniques used to measure fair value into three levels. Level 1 inputs are unadjusted quoted market prices in active markets for identical assets and liabilities that the Company has the ability to access at the measurement date. Level 2 inputs are inputs other than quoted prices within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for assets or liabilities, and reflect the Company’s own assumptions about the assumptions that market participants would use in pricing the asset or liability.

The estimated fair value of the Company’s assets and liabilities as of December 31, 20172020 and December 31, 20162019 were as follows (in thousands):

Revenue recognition- The Company recognizes revenues under ASC 842 Leases (“ASC 842”) and ASC 606 Revenue from Contracts with Customers (“ASC 606”).
Rental income from medical services is recognized – The Company recognizes revenues under ASC 842 when services have been rendered and collectability is reasonably assured, on either a fee per use or revenue sharing basis. The terms of the contracts do not contain any guaranteed minimum payments. The Company’s contracts are typically for a ten year10-year term and are classified as either fee per use or retail. Retail arrangements are further classified as either turn-key or revenue sharing. Rental incomeRevenues from fee per use contracts is determined by each hospital’s contracted rate. Rental income isRevenues are recognized at the time the procedures are performed, based on each hospital’s contracted rate and the number of procedures performed. Under revenue sharing arrangements, the Company receives a contracted percentage of the reimbursement received by the hospital. The amount the Company expects to receive is recorded as revenue and estimated based on historical experience. Rental incomeRevenue estimates are reviewed periodically and adjusted as necessary. Under turn-key arrangements, the Company receives payment from the hospital in the amount of itsthe hospital’s reimbursement from third party payors, and the Company is responsible for paying all the operating costs of the equipment. Operating costs are determined primarily based on historical treatment protocols and cost schedules with the hospital. The Company records an estimate of operating costs which are reviewed on a regular basis and adjusted as necessary to more accurately reflect the actual operating costs. For turn-key sites, the Company also shares a percentage of net operating profit. The Company records an estimate of net operating profit based on estimated revenues, less estimated operating costs. The operating costs and estimated net operating profit are recorded as other direct operating costs in the consolidated statement of operations.

operations. As of December 31, 2020 and 2019, the Company recognized revenues of approximately $16,204,000 and $19,396,000 under ASC 842, respectively.

Patient income – The Company has stand-alone facilities in Lima, Peru and Guayaquil, Ecuador, where a contract exists between the Company’s facilities and the individual patient treated at the facility. Under ASC 606, the Company acts as the principal in this transaction and provides, at a point in time, a single performance obligation, in the form of a Gamma Knife treatment. Revenue related to a Gamma Knife treatment is recognized on a gross basis at the time when the patient receives treatment. There is no variable consideration present in the Company’s performance obligation and the transaction price is agreed upon per the stated contractual rate. GKPeru's payment terms are typically prepaid for self-pay patients and insurance provider payments are paid net 30 days. GKCE's patient population is primarily covered by a government payor and payments are paid approximately 30 to 60 days upon invoice. The Company did not capitalize any incremental costs related to the fulfillment of its customer contracts. Accounts receivable earned by GKPeru were not significant for the year ended December 31, 2020 and 2019. GKCE's accounts receivable were $467,000 for the year ended December 31, 2020. As of December 31, 2020 and 2019, the Company recognized revenues of approximately $1,633,000 and $1,209,000 under ASC 606, respectively.
Stock-based compensation – The Company measures all stock-based compensation awards at fair value and records such expense in its consolidated financial statements over the requisite service period of the related award. See Note 89 for additional information on the Company’s stock-based compensation programs.

Costs of revenue –The Company's costs of revenue consist primarily of maintenance and supplies, depreciation and amortization, and other operating expenses (such as insurance, property taxes, sales taxes, marketing costs and operating costs from the Company’s retail sites). Costs of revenues are recognized as incurred.

Sales and Marketing– The Company markets its services through its preferred provider status with Elekta and a direct sales effort led by its Senior Vice President of Sales and Business Development, its President and Chief Financial and Operating Officer and its Chief Operating Officer. The Company’s current business is the outsourcing of stereotactic radiosurgery services and radiation therapy services. Executive Officer (“CEO”).
The Company typically provides the equipment, as well as planning, installation, reimbursement and marketing support services.

Income taxes – The Company accounts for income taxes using the asset and liability method. Under this method, deferred tax assets and liabilities are determined based on differences between the financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse.

NOTE 2 – ACCOUNTING POLICIES (CONTINUED)
The Company accounts for uncertainty in income taxes as required by the provisions of ASC 740 Income taxes (“ASC 740”), which clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to estimate and measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement. It is inherently difficult and subjective to estimate such amounts, as this requires the Company to determine the probability of various possible outcomes. The Company considers many factors when evaluating and estimating the Company’s tax positions and tax benefits, which may require periodic adjustments and may not accurately anticipate actual outcomes.
See Note 78 for further discussion on income taxes.

Functional currency– Based on guidance provided in accordance with ASC 830,Foreign Currency Matters (“ASC 830”), the Company analyzes its operations outside the United States to determine the functional currency of each operation. Management has determined that these operations are initially accounted for in U.S. dollars since the primary transactions incurred are in U.S. dollars and the Company provides significant funding towards the startup of the operation. When Management determines that an operation has become predominantly self-sufficient, the Company will change its accounting for the operation to the local currency from the U.S. dollar.

The Company analyzed it’s Gamma Knife site in Peru under ASC 830 as of December 31, 2020 and 2019 and concluded the functional currency was the U.S. dollar. As facts and circumstances change, the Company will revisit this conclusion.

Asset Retirement Obligations –Based on the guidance provided in ASC 410Asset Retirement Obligations (“ASC 410”), the Company analyzed its existing lease agreements and determined an asset retirement obligation (“ARO”) exists to remove the respective units at the end of the lease terms. The fair valueAs of December 31, 2020, four (4) of the Company's Gamma Knife customers notified the Company of their intent to terminate their contracts at the contract lease term. The Company recorded an ARO liability is not reasonable to estimate at this time, due to uncertainties about timing, cost and, outcome of the ARO, therefore nofor these four (4) sites, using estimates from Elekta. No liability has been recorded as of December 31, 2017.2020 for the remaining Gamma Knife sites, or as of December 31, 2019, because it is uncertain these units will be removed and the Company historically has not removed the Gamma Knife equipment at the end of the lease term. The Company will re-evaluate this positionthe need to record additional ARO liabilities on a periodic basis when facts and circumstances change that could affect this conclusion.

Earnings per share– Basic earnings per share excludes dilution and is computed by dividing income available to common shareholders by the weighted average number of common shares outstanding for the year. The fully vested restricted stock units not issued and outstanding, are also included therein. Diluted earnings per share reflect the potential dilution that could occur if common shares were issued pursuant to the exercise of options or warrants.

12

Because the Company reported a loss for the year ended December 31, 2020, the potentially dilutive effects of approximately 13,000, of the Company's unvested restricted stock awards were not considered for the reporting periods.

the Company’s stock incentive plan - see Note 2 – Accounting Policies (continued)

9 for further discussion. Based on the guidance provided in accordance with ASC 260, the weighted average common shares for basic earnings per share, for the year ended December 31, 2019 excluded the weighted average impact of the unvested performance share awards. These awards were legally outstanding but not deemed participating securities and therefore were excluded from the calculation of basic earnings per share. The unvested shares were also excluded from the denominator for diluted earnings per share because they were considered contingent shares not deemed probable as of December 31, 2019.

The following table illustrates the computations of basic and diluted earnings per share for the years ended December 31, 2017, 20162020 and 2015.

ACCOUNTING POLICIES (CONTINUED)

Long lived asset impairment – The Company assesses the recoverability of its long-lived assets when events or changes in circumstances indicate their carrying value may not be recoverable. Such events or changes in circumstances may include: a significant adverse change in the extent or manner in which a long-lived asset is being used, significant adverse change in legal factors or in the business climate that could affect the value of a long-lived asset, an accumulation of costs significantly in excess of the amount originally expected for the acquisition or development of a long-lived asset, current or future operating or cash flow losses that demonstrate continuing losses associated with the use of a long-lived asset, or a current expectation that, more likely than not, a long-lived asset will be sold or otherwise disposed of significantly before the end of its previously estimated useful life. The Company performs impairment testing at the asset group level that represents the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. The Company assesses recoverability of a long-lived asset by determining whether the carrying value of the asset group can be recovered through projected undiscounted cash flows over their remaining lives. If the carrying value of the asset group exceeds the forecasted undiscounted cash flows, an impairment loss is recognized, measured as the amount by which the carrying amount exceeds estimated fair value. An impairment loss is charged to the consolidated statement of operations in the period in which management determines such impairment. NoAs of December 31, 2020, the Company determined circumstances existed indicating its assets could be impaired, concluded an impairment existed, and recognized a loss on the write down of impaired assets of $8,264,000. NaN such impairment has been noted as of December 31, 20172019. See Note 3 - Property and 2016.

RecentlyEquipment for further discussion.

Goodwill and intangible assets - The Company recorded goodwill of $1,265,000 and an intangible asset with a fair value of $78,000 as part of the Acquisition in June 2020. The intangible asset identified was GKCE's trade name and the Company assigned an indefinite useful life to the asset. Based on the guidance provided in accordance with ASC 350 Intangibles-Goodwill and Other (“ASC 350”), the Company does not amortize the intangible asset because it has an indefinite life. The Company assesses goodwill at the reporting unit level, which has been determined to be GKCE. Each reporting period, the Company assesses whether events or circumstances continue to support an indefinite useful life for the intangible asset. Per ASC 350, the Company tests goodwill and intangibles for impairment annually or as events or circumstances change that indicate the fair value may be below the carrying amount. As of December 31, 2020, there has been no change to the Company's assessment of the value of intangible assets or goodwill.
Acquisitions - The Company records acquisitions according to ASC 805 Business Combinations (“ASC 805”) using the acquisition method of accounting. Under the acquisition method of accounting, all assets acquired, including goodwill and other intangible assets, should be stated at fair value at the time of acquisition. The allocation of purchase price consideration is preliminary, pending the completion of the fair value of certain tangible, intangible assets, and residual goodwill. During the measurement period, which can be no more than one year from the Closing Date, the Company expects to continue to obtain information to assist in determining the final fair value of assets acquired. See Note 4 - GKCE Acquisition for further discussion on acquisitions.

Accounting pronouncement issued and adopted accounting pronouncementsIn May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09,Revenue from Contracts with Customers (Topic 606), ("ASU 2014-09"), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in United States Generally Accepted Accounting Principles (“GAAP”) when it becomes effective. In December 2016, FASB issued ASU 2016-20Technical Corrections and Improvements to Topic 606, (“ASU 2016-20”), which affects some narrow aspects of ASU 2014-09. The new standard is effective for the Company for annual reporting periods beginning after December 15, 2017 and interim reporting periods therein. Early application is permitted for reporting periods beginning after December 15, 2016. The standard permits the use of either the retrospective or cumulative effect transition method. The Company performed an analysis to determine if its revenue agreements with customers fall under the scope of ASU No. 2016-02Leases (“ASU 2016-02”) or ASU 2014-09 and concluded that, other than with respect to the Company’s stand-alone facility in Lima, Peru, ASU 2014-09 was not applicable. The Company has a project team in place to analyze the impact of ASU 2014-09 to its revenue stream in Peru. The Company believes it is following an appropriate timeline to allow for proper recognition, presentation, and disclosure upon adoption of ASU 2014-09. The Company intends to adopt the standard at the date required for public companies, but has not yet selected a transition method. The Company does not anticipate any change to its IT control environment from the adoption of ASU 2014-09. The Company expects to have significant additional footnote disclosures related to accounting policies, practices and significant assumptions used for arrangements governed by ASU 2014-09.

In February 2016, the FASB issued ASU 2016-02, which requires lessees to recognize, for all leases, at the commencement date, a lease liability, and a right-of-use asset. Under the new guidance, lessor accounting is largely unchanged. The new guidance is effective for the Company on January 1, 2019. Early adoption is permitted. The Company is evaluating the effect that ASU 2016-02 will have on its consolidated financial statements and related disclosures. The Company performed an analysis to determine if its revenue agreements with customers fall under the scope of ASU 2016-02 or ASU 2014-09 and concluded that, other than with respect to the Company’s stand-alone facility in Lima, Peru, ASU 2016-02 applied.

The new guidance is effective for the Company for interim and annual periods beginning after December 15, 2016. The Company adopted ASU 2016-09 on January 1, 2017. The Company elected to estimate the impact of forfeitures. There was no material impact on the consolidated financial statements and related disclosures.

In June 2016, the FASB issued ASU No. 2016-13Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which requires measurement and recognition of expected credit losses for financial assets held.2018-03.

The DFC loan is denominated in Mevion.U.S. dollars, which is also the currency of Ecuador. The price adjustments will be paid by the Company in the post-closing period with the adjustments related to the amount of working capital that GKCE had as of the Closing Date.

Based on guidance provided incontingent consideration at the Closing Date.


The acquisition has been accounted for according to ASC 320Investments–Debt805 using the acquisition method of accounting. Under the acquisition method of accounting, all assets acquired, including goodwill and Equity Securities (“ASC 320”) and Staff Accounting Bulletins (“SAB”)Topic 5M Other Than Temporary Impairment (“OTTI”) of Certain Investments in Equity Securities (“SAB Topic 5M”), the Company analyzed the related events of Mevion, that occurred in the second and third quarters of 2015 and its impact on the Company’s investment. The Company determined that these circumstances indicated a decline in value of its Mevion investment that was other-than-temporary, and concluded that a write-down of the carrying valueother intangible assets, should be recognized. As of June 30, 2015, the Company adjusted its investment in Mevion to the estimatedstated at fair value at the time of approximately $600,000 and recorded a $2,114,000 impairment loss.acquisition.

NOTE 7 - LEASES
The Company determines if a contract is a lease at inception. Under ASC 842, the Company is a lessor of equipment to various customers. Leases that commenced prior to ASC 842 adoption date were classified as operating leases under historical guidance. As the Company has elected the package of practical expedients allowing it to not reassess lease classification, these leases are classified as operating leases under ASC 842 as well. All of the Company’s lessor arrangements entered into after ASC 842 adoption are also classified as operating leases. Some of these lease terms have an option to extend the lease after the initial term, but do not contain the option to terminate early or purchase the asset at the end of the term.
The Company’s Gamma Knife and PBRT contracts with hospitals are classified as operating leases under ASC 842. The related equipment is included in medical equipment and facilities on the Company’s consolidated balance sheets (see further discussion at Note 7 – Income Taxes

2). As all income from the Company’s lessor arrangements is solely based on procedure volume, all income is considered variable payments not dependent on an index or a rate. As such, the Company does not measure future operating lease receivables.

The Company’s lessee operating leases are accounted for as right-of-use (“ROU”) assets, other current liabilities, and lease liabilities on the consolidated balance sheets. Operating lease ROU assets and liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. The Company’s operating lease contracts do not provide an implicit rate for calculating the present value of future lease payments, so the Company determined its incremental borrowing rate to be in the range of approximately 4.0% and 6.0% by using available market rates and expected lease terms. The operating lease ROU assets and liabilities also include any lease payments made and excludes lease incentives and initial direct costs incurred. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. The Company’s lessee operating lease agreements are for administrative office space and related equipment, and the agreement to lease clinic space for its stand-alone facility in Lima, Peru. These leases have remaining lease terms between 2 and 3 years, some of which include options to renew or extend the lease. As of December 31, 2017, 20162020, operating ROU assets and 2015 the Company recorded income tax provision benefit of $1,103,000, and income tax provision expense of $943,000 and $434,000, respectively. On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the "Tax Act"). The Tax Act makes broad and complex changes to the U.S. tax code that affect fiscal 2017, including, but not limited to requiring a one-time transition tax on certain unrepatriated earnings of foreign subsidiaries that is payable over eight years. The Tax Act also establishes new tax laws that will affect 2018 and later years, including, but not limited to, a reduction of the U.S. federal corporate tax rate from 34% to 21%, a general elimination of U.S. federal income taxes on dividends from foreign subsidiaries, net operating loss deduction limitations, a base erosion, anti-tax abuse tax and a deduction for foreign-derived intangible income and a new provision designed to tax global intangible low-taxed income. As these provisions do not apply until 2018 the Company continues to evaluate the impact of such provisions of the Tax Act. As a result of the Tax Act, the Company revalued its federal and state deferred tax liabilities based on a 21% tax rate as opposed to a 34% tax rate. The net effect of this change on the Company’s income tax provision forwere $886,000.
During the year ended December 31, 20172020, the Company elected to not renew its lease for a satellite office in Fairfield, California. The Company previously included the renewal term in its assessment of the lease term for the ROU asset and liability. The Company accounted for this change as a lease reassessment under ASC 842. At the reassessment date, the remaining lease balance was not material to the Company's consolidated balance sheets and the Company wrote off the related ROU assets and liabilities of $67,000. Also during the year ended December 31, 2020, the Company agreed to a rent increase for its clinic space for its stand-alone facility in Lima, Peru. The rent increase was effective as of January 1, 2020 and the Company increased the related ROU assets and liabilities by $135,000.

On December 22, 2017, the SEC staff issued Staff Accounting Bulletin No. 118 (“SAB 118”) which provides guidance on accounting for the tax effects of the Tax Act. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740Income taxes (“ASC 740”). In accordance with SAB 118 a company must reflect the income tax effects of those aspects of the tax Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. Additional work is necessary for a more detailed analysis of our deferred tax assets and liabilities. Any subsequent adjustment to these amounts will be recorded to current tax expense in the quarter of 2018 when the analysis is complete.

During the year ended December 31, 2017, the Company did not recognize a provisional income amount for the transition tax, due to the fact the foreign subsidiaries have accumulated losses. The final effects of the Tax Act may differ from these provisional amounts, due to among other things, changes in interpretations of the Tax Act, any legislative action to address questions that arise because of the Tax Act, any changes in accounting standards for income taxes or related interpretations in response to the Tax Act, any updates or changes to the estimates utilized to calculate provisional amounts, or actions we may take as a result of the Tax Act. The associated accounting for the Tax Act is expected to be completed when our 2017 US corporate income tax return is filed in 2018.

Utilization of the domestic NOLnet operating loss and tax credit forwardscarryforwards may be subject to a substantialan annual limitation due to the ownership change limitations that may have occurred or that could occur in the future, as requiredprovided by the Internal Revenue Code Section 382,of 1986, as well asamended (the “Code”), and similar state provisions. In general, an “ownership change,” as defined by the code, results from a transaction or series of transactions over a three-year period resulting in an ownership change of more than 50 percentage points of the outstanding stock of a company by certain stockholders or public groups. Any annual limitation may result in the expiration of all or a portion of the NOL or tax credit carryforwardsnet operating losses and credits before utilization.

At December 31, 2017,2020, the Company has a capital loss carryforward for federal income tax return purposes of approximately $3,895,000$2,586,000 which starts to expire in 2019.2021. The Company has capital loss carryforwards for state income tax purposes of approximately $177,000$129,000 which starts to expire in 2018.

Due to the uncertainty that the Company will generate capital gains in future years to utilize its capital loss carryforward, a valuation allowance has been placed against the deferred tax asset. 2021.

Due to uncertainty surrounding the realization of impairment losses, capital losses and foreign operating losses in future years, the Company has placed a valuation allowance against a portion of its net domestic and foreign deferred tax assets. The net valuation allowance decreased by $303,000,$243,000 and increased $25,000, and $792,000$175,000 for the tax years ended December 31, 2017, 2016,2020 and 2015,2019, respectively.

During the year ended December 31, 2019, the Company released the valuation allowance related to GKPeru deferred tax assets, which resulted in an income tax benefit of $104,000. The Company concluded, based upon the preponderance of positive evidence (i.e. cumulative profit before tax adjusted for permanent items over the previous twelve quarters, a history of taxable income in recent periods, and the current forecast of income before taxes for GKPeru going forward) over negative evidence and the anticipated ability to use the deferred tax assets, that it was more likely than not that the deferred tax assets will be realized. If there are unfavorable changes to actual operating results or to projections of future income, the Company may determine that it is more likely than not such deferred tax assets may not be realizable.
The tax return years 20122016 through 20172019 remain open to examination by the major domestic taxing jurisdictions to which the Company is subject. In 2019, the Company settled a New York State examination for tax years 2015 through 2017 with no material adjustments. Net operating losses generated on a tax return basis by the Company for calendar years 1999 through 2004, 2009, 2010, 2012, 2014, 2015, 2016, 2017 and 20172018 remain open to examination by the major domestic taxing jurisdictions.

The Company has adopted accounting standards which prescribe a recognition threshold and measurement attribute for the financial statement recognition and measurement of uncertain tax positions taken or expected to be taken in a company's income tax return, and also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. Additionally, these accounting standards specify that tax positions for which the timing of the ultimate resolution is uncertain should be recognized as long-term liabilities.

STOCK-BASED COMPENSATION EXPENSE

Incentive Compensation Plan

In June 2010 shareholders approved an amendment and restatement of the Company’s stock incentive plan, renaming it the Incentive Compensation Plan (the “Plan”), and among other things, increasing the number of shares of the Company’s common stock reserved for issuance under the Plan to 1,630,000. The Plan provides that the shares reserved under the Plan are available for issuance to officers of the Company, other key employees, non- employee directors, and advisors. The Plan is a successor to the Company’s previous plans, and any shares awarded and outstanding under those plans were transferred to the Plan. No further grants or share issuances will be made under the previous plans. On June 27, 2017,21, 2019, the Company’s shareholders approved an amendment and restatement of the Plan in order to extend the term of the Plan by two years to February 22, 2020.2022. As of December 31, 2017,2020, approximately 375,000437,000 shares remain available for grant under the Plan.

The Plan provides for nonqualified stock options, qualified (or incentive) stock options and stock grants. The Plan has a provision to reduce the number of shares reserved for award and issuance under the Plan by a ratio of 1.59 shares of common stock for each share of common stock that is issued pursuant to a Full Value Award (stock grant).

The Plan also provides for an Incentive Bonus Program with incentive bonus opportunities through performance unit awards and special cash incentive programs tied to the attainment of pre-established performance milestones.

Provisions of the Plan include an automatic annual grant to each non-employee director of options to purchase up to 2,000 shares on the date of the Company’s Annual Shareholder Meeting, at an exercise price equal to the market price of the Company’s common shares on that date, an automatic annual grant of 500 restricted stock units of the Company’s common shares and an annual cash retainer fee for Board or Board Committee service, which may be converted to restricted stock unit awards. Options and restricted stock units awarded under the automatic annual grant program for non-employee directors vest after one year. Restricted stock units awarded in lieu of retainer fees vest quarterly, over a one year period. These awards become outstanding upon the conclusion of the individual Board members service on the Company’s Board of Directors. Other options may vest fully and immediately, or over periods of time as determined by the Plan Administrator, but no longer than seven years from the grant date. Discretionary options currently awarded under the Plan vest over a period of 5 years.

Under the Plan, a total of 241,000456,000 restricted stock units have been granted, consisting of 34,00043,000 of annual automatic grants to non-employee directors and the corporate secretary, 197,000293,000 of deferred retainer fees to non-employee members of the Board, and 10,00020,000 grants issued in lieu of commission, to one employeetwo (2) employees of the Company.Company and 100,000 restricted stock units issued to the CEO during 2020, see further discussion below.

Certain Executive Equity Awards
Effective May 4, 2020, the Company appointed Raymond C. Stachowiak as Interim President and Chief Executive Officer (“Interim CEO”).

As of December 31, 2017, the Company achieved one of the certain performance metrics under the Award Agreements and recognized stock compensation expense of approximately $108,000 related to these awards. As of December 31, 2017 it is not probable that any of the remaining required metrics for vesting will be achieved. The unrecognized stock-based compensation expense for these awards was approximately $434,000$421,000 and unvested restricted stock awards wereof approximately 129,000 were returned to the plan as of DecemberMarch 31, 2017. If and when the Company determines that the remaining performance metrics’ achievement becomes probable, the Company will record a cumulative catch-up stock-based compensation amount and the remaining unrecognized amount will be recorded over the remaining requisite service period of the awards.

The Company’s stock-based awards to employees are calculated using the Black-Scholes options valuation model. The Black-Scholes model was developed for use in estimating the fair value of traded options which have no vesting restrictions and are fully transferable. In addition, the Black-Scholes model requires the input of highly subjective assumptions including the expected stock price volatility. The Company’s stock-based awards have characteristics significantly different from those of traded options, and changes in the subjective input assumptions can materially affect the present value estimates. For these reasons, management believes that the existing models do not necessarily provide a reliable single measure of the fair value of its stock-based awards to employees.

The fair value of the Company’s option grants issued during 2017, 20162020 and 20152019 were estimated using assumptions for expected life, volatility, dividend yield, forfeiture rate, and risk-free interest rate which are specific to each award as summarized in the following table. The estimated fair value of the Company’s options is amortized over the period during which the optionee is required to provide service in exchange for the award, usually the vesting period.

The fair value of the Company’s option grants under the Plan in 2017, 20162020 and 20152019 was estimated using the following assumptions:

  2017  2016  2015

Repurchase of Common Stock, Common Stock Warrants and Stock Options

In 1999 and 2001, the Board of Directors approved resolutions authorizing the Company to repurchase up to a total of 1,000,000 shares of its own stock on the open market, which the Board reaffirmed in 2008. There were no shares of the Company repurchased during 2017, 20162020 or 2015.2019. There are approximately 72,000 shares remaining under this repurchase authorization.

Note 12 – Note, Warrant, & Common Stock Purchase Agreement (continued)

During the year ended December 31, 2016, the Company paid down the Notes. Based on the guidance provided in accordance with ASC 405Extinguishment of Liabilities (“ASC 405”) and ASC 470Debt Modifications and Extinguishments (“ASC 470”), the pay-down of the Notes is considered an extinguishment of debt and, as such, the difference between the net carrying amount of the Notes and the costs of extinguishment was recognized as a loss on the Company’s condensed consolidated statements of operations. During the year ended December 31, 2016, the Company recorded a loss on early extinguishment of debt of $108,000. The Notes were issued with common stock warrants with an estimated fair value of $145,000. The unamortized balance of the discount on the Notes, of $80,000, and deferred fees incurred from the issuance of the Note of approximately $28,000, were recorded as a loss on early extinguishment.

Concurrently with the Note and Warrant Purchase Agreement, the Company entered into a common stock purchase agreement (the “Common Stock Purchase Agreement”) with one member of the Company’s Board of Directors to sell, in a private offering, 100,000 shares of the Company’s Common Stock (the “Private Placement Shares”), for gross proceeds of $220,000 (the “Common Stock Offering” and, together with the Notes and Warrants Offering, the “Private Offering”). The Common Stock Purchase Agreement contains terms and conditions that are customary for a transaction of this type.

The Company received gross proceeds of $1,220,000 in the Private Offering, which were used, together with cash on hand, to make two payments of $1,000,000 each to Mevion as deposits pursuant to the terms of purchase commitments with Mevion.
